Re: Charpy Impact Test Conversion. It is also important to understand the similarities and differences between these two common impact test methods. In the Charpy method, the notch is kept facing away from the pendulum horizontally and the striking point is in the middle of the sample. I cannot see how the value would be acceptable if the material specification requests the test to be performed to the Izod method? A great deal of data, albeit older (mid-20th century), has been collected using Izod testing, and it would be of great value to be able to use it today in some fashion. charpy impact test equation. In this instance, the data were highly correlated, but one must keep in mind that the data represents different heats of steel produced years apart (1982 vs. 1954) and heat treated in separate processing equipment. The Charpy method has two notches, namely, U notch and V notch. (LogOut/ 3 Record your new value. Conversions for the different units used for izod impact: If you know J/m and want ft-lbs/in, then multiply by 0.0187, If you know ft-lb/in and want kJ/m, then multiply by 2.1. There are varying configurations of round specimens versus square specimens and single notched specimens versus those with up to three notches.
